Yellow veins and cearly leaves

Hi guys, i recently encountered a problem on some leaves of my plant that i cannot quite explain...

i am relatively new to cannabis growth (my 3rd time) but this doesn't seem right.
the plant is an OG kush in its mid-late flowering stage and recently saw emerge some "yellowy veins", not leaves, mostly on top of the plant... in addition to this, the leaves started curling a bit yesterday (i'll attach some pictures so you can see by yourself).
the plant seemed to be relatively healthy before that and i am afraid it will disturb the flowering...

would you guys have any idea what is going on and what i could to to try and fix it ?

thanks :)

temperature is round 19°C or round 70°F; i am growing in a prepared soil mix that has not shown any sign of weakness so far (i am not controlling humidity since i am still a beginner and don't have all the required equipment...)
i feed them with the Bio-Bloom from Biobizz (5ml/L of water)
and i will provide you shortly with closer up pictures.
thank you a lot for your help :)

(the plant on the right, growing in the same big pot seems to be fine it's why i find that weird)

Rooms a little chilly but that’s not the problem.

looks like interveinal chlorosis usually that’s mag deficiency but could be missing some iron too.

what kind of lighting you using as well?
 
okay thank you ! could the Ph be to blame ? the only thing is that i am using the same for both plants aand only the top of the left one is reacting like this...
as for the lighting, i am using the Florastar agro 8U-250W-2100°K (11200lum).
 
as for the temperature, it is what i first thought and then i read about an article which said mostly-indi strains tended to resist better lower temperature because of their genetic origin (like they were first cultivated in Nepal mountains or something similar).
 
yes PH could be a cause so before you do anything wait for a second opinion
I think it’s mag def so some epsom salt would fix that but if it’s ph related might just burn or cause a lockout

I grow a different method and don’t really care about or monitor PH anymore so I often over look it now a days

Reccomended dose of bio bloom is 2-4 ml per litre. Initial dose is 1ml per litre and it is one of six bottles in their feeding schedule. So you probably not gonna be able to finish it with only one bottle...

thank you for this :) but would you have any idea of the potential cause of the problem ?
 
Something you gave them screwed them up, not from lack of nutes. Check your soil, transplant into promix and use a good nute lineup like Ionic or Soul Synthetics. Keep a fan on them too, and flush with just water at this point. I would lay off of whatever solution you were giving them for a good while. If you foliar with just water it will help them flush out faster
 
All you really need to get started is some good promix, small bottle of Calmag, Grow, Bloom, Pk boost. That will get the job the anything else like micros and aminos can tune it in more but keep it simple at first.
 
Its like a calcium deficiency but there on the veins rather then the leaf?.Ive seen this before but im unable to give advice sorry.I know if left unchecked it will hurt yield.
I grew a plant in hydro that looked the same,more calmag seemed to make it worse.i phone 236.JPG
 
Does it appear on the whole plant or is it just on specific branches? It think your biggest concern should be how you buds look like. The one you have posted have pistils already darken and it seems to me that she is dealing with whorled phylotaxy all the way down...
